OIL BURNER.

Application filed May 15, 1923. Serial No. 639,055.

To all whom it may concern:

Be it known that we, W'ILLIAM ROCKEFEL-;

C pings with the fuel supply tank.

Another object is to provide an oil burning stove having a burner nozzleand a fuel supply tank, the fuel oil being delivered to the burner thrua feed pipe by a pressure pump.

Still another object is to provide an igniting pan beneath. the burnernozzle, and means for removing said pan from beneath the nozzle when thesurface of the oil there in is to be fired. These and other objects willbecome apparent in the description below, in which characters ofreference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a sectional elevationalview taken substantially centrally thru the entire stove.

Figure 2 is a front elevational view showing the external construction.

Figure 3 is a bottom plan view of Figure 1.

Figure 4 is a cross sectional View taken on line 44 of Figure 2, andillustrates the means by which the igniting pan is removed.

Referring indetail to the drawing, the numeral indicates an annularapron which provides a lower casing. Said casing has an opening thereinwhich is normally covered by a hinged door 11. A conical hood 12 inwhich a plurality of vent holes 13 is provided, has a flange 14 thereonriveted to the upper edge of the apron 10. A cylindrical member 15 formsa hood and is provided with a relatively large opening covered by ahinged door 16, the latter hav- 1 ing a latch 17 thereon to retain saiddoor in closed position. Said hood is seated upon the upper edge of aconical sleeve 18. The lower portion of the conical sleeve is formedinto a cylindrical sleeve 19 at the lower edge of which an annular bedplate 20 is seated. Between this plate and a similar one 21 above it, aquantity of asbestos 22 is stored in order to separate the hood chamber23 from thefapron chamber 24.

A ring strap 25 is secured to the interior wall of the apron at itslower end, and is connected to a smaller ring 26 by a plurality of legs27 said rings forming a supporting frame for a tank 28 in which the fuelsupply 29 is stored. The front of the tank facing the door opening, isprovided with a level glass 30 attached to the tank at the bottom andtop in the usual manner. One end ofa filler pipe 31 which is providedwith a shut-off valve 32, is connected to the lower portion of the tank,the opposite end passing upwardly within the apron l0 and projectingthru the conical head 12, and being surmounted by a cap 33 which may beremoved to fill the tank. A second pipe, also communicating with thetank, projects thru the head 12 and is connected thru a suitable hose orthe like, to an exhaust pressure pump (not shown). 35 is connected tothe lower end of the tank, and extends vertically upward, having itsupper end formed into a U-shaped fixture, the lower arm 36 beingprovided with the usual relatively small outlet port 37 thru which thefuel oil passes. A diffusing disc 38 is supported by the remaining armof the U-shaped fixture above the jet.

The upper door 16 has a platform mounted thereon upon which a pan 39 issupported.

In using the stove, a pump is required, which induces a pressure abovethe liquid 29 in the tank 28. As aforementioned, the pump is preferablyconnected to pipe 34. The pressure on the fuel oil will cause the latterto pass upward thru the feed pipe 35 to the U-shaped nozzle fixture.Before ignition of the oil, a quantity of oil is allowed to drip intothe pan. As the pan is carried upon the platform 40 of the door 16, itis in an accessible position when said door 16 is opened. In order tostart the stove burning, the pipe arm 36 is first heated by igniting theoil in the pan. The oil, in passing thru the port 37 of the heated pipearm 36, will be pre-heated, and hence readily vaporized and ignited bythe. flames in the pan. When all the oil in the pan has been consumed,the atomized oil passing from the jet will be The lower end of a feedpipe ignited of itself, and the flames in passing therefrom Will bedifiused over the entire chamber 23 by the disc 38.

Vi e claim A heater comprising a body having an upper and lowercompartment, thecompartments being separated by an asbestos layer, saidcompartments having openings therein, hinged doors adapted to cover saidopenings, as fuel tank in the lower compartment,

' a feed pipe extending vertically from the tankto the uppercompartment, the upper end of said feed pipe being formed into aU-shaped fixture, said fixture having a port 7 15 therein, a diffusingdisc mounted above said port adapted to spread the flames of the burningoil, an igniting pan belovvsaid port adapted to receive the oilfrom saidport before ignition, the burning oil in said pan being adapted to" heatsaidffeed pipe, as-plat form beneath said port rigidly securedto thedoor, said platform adapted to "be rotated with the door and shift thepan therewith,

the" platform having a curved edge generated by using the door pivot asa center.
